To allwhom it may concern:

speci cation.

This invention relates to an apparatus for. i attaching or securing coupling nutsv on union oints for use with pipes, faucets andother' fittings.

Fig.5 is a. view like the upper'portion of Fig. 1 showing the machine operating on a bath fittingor double .co'ck,- and Figs. .5, 6 and 7 j i are views .showing the application of the ring to its-seat or groove to form a-retflining collar. 7

Thesupper' end of the standard 12 is: slightly reduced indiameter as at 23 togive room for the die whenithesleeve 14.

made in one side of the sleeve14'at such a point as to be in the plane of the top of the standard 12 when said sleeve is elevatedto. enable the rings or collars C being mserted within the sleeve and rest on the top of the standard, (see Figs. 1 and 4).

' In the operation of the machine the sleeve 14 is raised b the lever 15 to the position indicated in ig. Land a; rin or collar C inserted through the slot 24 in the sleeve onto the" top of the standard 12 where it rests. The shank of a fitting such as A or B or other type of fittin is then inserted through the upper end of e sleeve and the ring or collar C, which has an opening sufii-;

ciently large for the passage of the shank and into the socket 13, where it rests on the bottom ofthe same, the couplir ig1 nut D being first slipped on the stem. e de th of the socket 13 is such that the circum erential groove a is exactly opposite the ring.

The lever 15 is now depressed to move thesleeve 14 in a longitudinal direction, thus bringing the conical die 22 into contact with the exterior. of the stationary ring on all sides. The movement gradually or progressively compresses or' re uces the diameter of the ring and forces it into the groove 0 in the shank. This compressing action continues until the die 22 has been depressed below the ring or collar as shown in Figs. 2 and 4, at which time the ring will be firmly seated in the groove and project. a suflicient distance from the shank to engage the inturned flange d on the'coupling nut D. As the conical die 22 is circularin cross section it bears equally on all sides of the ringer collar while seatin it in the grooved, so that at the completlon of the operation the peripher of sald collar is a true circle and concentric with the shank and the interior of the cou lin nut.

From t e a ove description, it is clear that the broad idea of seatin rings by the aforesaid machine in groove fittings con sists in the progressive application of pressure to the exterior of sald rings, particularly unbroken or continuous rings, the

movement beiin in a direction longitudinally of or axia y with the rin and fitting. The resultantof said pressure eing such as to com ress the ring radially on all sides and re uce its diameter. This result will be accomplished equally as well if the reducing means be fixed and the ring and fitting move, or if both the reducing means and the ring and fitting advance simulta= neously toward each other.

The improved means of securing coupling nuts for union joints on fittings of various kinds is cheap, simple, rapid and very efficient. The grooves in the shanks can be formed, the rings or collars produced, and the parts assembled without the employ utility.
